Hi Cleo, the mc correction will generate a segmentation file (something like cache.th20.abs.sig.ocn.mgh). The value at each vertex/voxel in this file correspond to the cluster that the vertex/voxel belongs to (if any). You can use this as the segmentation for mri_segstats and specify the gamma.mgh from your slope contrast to give you the average slope in each cluster.

Hi all,
My design is very simple: 1-group,1-variable 2-nuisance (age,gender). I just want to see the correlation between Cth and my variable. I obtain one cluster after mc-correction. (using freesurfer5)
There is any way to get the intercept,slope or r-pearson (in average) values of this particular cluster.
What I've done is transform this cluster in a label to then visually inspect the Graph Average ROI, but I want the numerical results.
Thanks in advance for your useful help.
Cleo.
